Megadeth
Device
Adrenaline Mob
Maybe a band like A Ghost Inside or For Today or something?

I was hearing rumblings of one of the Pantera related bands being involved. Kill Devil Hill or HellYeah makes the most sense but Down fits better. Not sure if Anselmo would play before Device (and although they shouldn't, Device had a strong debut for album sales, etc, so I bet they play before Megadeth).
